Historical Note

The ElectroData Corporation was taken over by Burroughs in June of 1956. ElectroData, originally a division of the Consolidated Electrodynamics Corporation, was spun off and then went public. This acquisition gave Burroughs a good start in the computer industry as ElectroData had built the Datatron 205 and was working on the Datatron 220.
